两性树脂解吸动力学的研究──温度对扩散系数的影响

本文采用浅床法对阳离子在弱酸强碱两性树脂相内的扩散速度进行了研究。发现温度升高 ,其粒内扩散系数增大 ,离子价态越高 ,扩散过程的活化能就越大 ,表明温度的改变对高价阳离子的扩散速度的影响更显著

Study of elution kinetics on amphoteric resin ——The effect on diffusion coeffcient with changing temperature

The particle diffusion in amphoteric resin containing carboxyl and quaternary nitrogen groups has been researched by shallow bed technique.The results have been made that the particle diffusion coefficients increase with rising temperature and activation energy of diffusion also increases with a rise in cation charges.The effect on diffusion velocity with increasing temperature is greater in higher charge cations.
